Are multiple Bluetooth adapters under Android possible?

Question

Are multiple Bluetooth adapters under Android possible (eg in order to be able to connect to more than 7 devices through these adapters)? Android API does not even mention the possibility of accessing more than one adapter: https://developer.android.com/reference/android/bluetooth/BluetoothAdapter.html#getDefaultAdapter()

I have no restrictions on root or running native code.

即使 Android API 不可能，如果 Android 设备有 OTG，那么 USB BT 加密狗可以连接到该设备（至少可以连接到 Android 多个 BT SPP 设备）。
